Racemization is considered to be an intrinsic stereochemical feature of free radical chemistry as can be seen in traditional radical halogenation reactions of optically active tertiary C-H bonds. If the facile process of radical racemization could be effe

Herein, we report the first protocol for visible-light-induced radical isocyanide insertion reactions between 3-(2-isocyanobenzyl)-indoles and bromodifluoroacetates or bromodifluoroacetamides. The protocol, which has good functional group tolerance and a broad substrate scope, constitutes an efficient and general route to difluoromethylated spiro[indole-3,3′-quinoline] derivatives.

The first asymmetric decarboxylative [4 + 3] annulation of propargylic carbamates with C,N-cyclic azomethine imines has been developed successfully by a copper-N-heterocyclic carbine system. This strategy led to a series of optically active isoquinoline-f

An efficient Lewis acid-catalyzed C(sp3)–C(sp3) bond forming annulation reaction has been developed. This strategy serves as a new method for the facile synthesis of tetrahydro-5H-isoquinolino[2,1-g][1,6]naphthyridine derivatives. A wide range of 2-methylquinoline-3-carbaldehydes and 1,2,3,4-tetrahydroisoquinolines can be applied for this process to afford structurally diverse tetrahydroprotoberberine derivatives in excellent yields.

We have reported previously the novel δ opioid agonist KNT-127 which showed high affinity and selectivity for the δ receptor. Moreover, the analgesic effect of subcutaneously administered KNT-127 was more potent than that of a prototypical δ agonist (-)-TAN-67 in the acetic acid writhing test. This study of the structure-activity relationship of KNT-127 derivatives focused on the introduction of substituents onto the 5′-, 6′-, 7′- or 8′-position of the quinoline ring and revealed that many derivatives with 5′- or 8′-substituents showed high affinities and selectivities for the δ receptor. Especially, SYK-153 with an 8′-OH group showed the highest affinity and the most balanced and highest selectivity for the δ receptor among the synthesized compounds.
